The controversy surrounding Nvidia chief executive Jensen Huang escalated on multiple fronts Sunday, as President Donald Trump defended the chipmaker's founder, China formally rejected the espionage allegations, and Nvidia shares fell roughly 5% in early trading, according to CNBC.

The developments came a day after Nvidia's board announced an independent investigation into Huang over his relationship with a businesswoman whom US intelligence officials suspected of acting on behalf of Beijing — a story first reported by the Financial Times and the New York Times and confirmed by the board in a statement posted to Nvidia's newsroom Saturday.

Background: The Board Inquiry and Huang's Admission

The board said Saturday that it was initiating the inquiry "in light of recent reporting that founder and CEO Jensen Huang has been the target of a foreign intelligence effort," stressing that it has "no reason to believe that either national security or Nvidia secrets were compromised" and that a committee of independent directors, assisted by outside counsel, will examine all available information.

Huang, in a message to Nvidia employees published under the title "A Message to Our Company," admitted he had been unfaithful to his wife and apologized to his family, saying he takes "full responsibility" and will cooperate fully with the investigation. He has led the company for more than three decades, building it into a roughly $4.5 trillion enterprise whose GPUs underpin nearly all frontier AI development at customers including OpenAI and Meta.

What changed Sunday is that the political and market consequences began to surface.

Trump: Huang Is an 'Honorable Guy'

Speaking to reporters, President Trump said he had not spoken to the Nvidia chief executive since news of the investigation emerged, but offered a pointed defense.

"I just know he's a fine person, but you never know what's going on," Trump said, adding that Huang had "done an amazing job for our country." Asked whether he wished he had acted on the intelligence when he was briefed on it last year — as the New York Times reported in late October — Trump replied: "No, I don't think so. I think he's an honorable guy."

The comment places the president at odds with the gravity of the intelligence assessment described in press reporting, and squarely protects the chief executive of the company most critical to US AI leadership.

Rubio Stays Silent

Secretary of State Marco Rubio refused to address the matter when questioned by reporters before flying to Paris for a G7 meeting.

"I can't comment on any of that. I just can't comment because of the nature of it," Rubio said, adding that he also could not comment on an "internal corporate matter" at Nvidia.

According to the New York Times, Rubio oversaw the drafting of a memo last spring, while serving in the Senate and as national security adviser, that warned the administration about Huang's relationship with the Chinese businesswoman.

Beijing Dismisses the Claims

China's government formally rejected the espionage narrative on Sunday. Foreign Ministry spokesperson Guo Jiakun told a daily press briefing that the allegations are "entirely groundless, speculative and intended to smear and malign China."

The businesswoman at the center of the reporting has been identified by the New York Times as Alice Huang — no relation to the Nvidia chief executive — who is linked to Singapore-based data center firm Megaspeed. US intelligence agencies, according to the newspaper, concluded she was acting on behalf of the Chinese government, and surveillance of her communications led to Jensen Huang's identification through a process known as "unmasking." Megaspeed has said its current leadership appointed external legal advisers to conduct an internal review of the allegations.

Markets Recoil

Nvidia shares dropped about 5% as the story dominated financial headlines into Monday's session, CNBC reported — a notable swing for the world's most valuable chipmaker, whose valuation makes even modest percentage moves meaningful for the broader AI trade and index funds.

Analysts quoted by the Los Angeles Times argued the affair and the board inquiry have tarnished the image of a leader long regarded as Silicon Valley's most consistent steward of the AI boom, even as the board's statement made clear that Huang's role is not currently under threat and that it has "confidence in Jensen and his leadership team."

What Comes Next

Three threads will define the story's second week. The board's committee, with outside counsel, will examine what information existed and whether any company secrets were exposed. Megaspeed's external legal review in Singapore remains open. And in Washington, lawmakers may press for briefings on what intelligence agencies knew and when — a question with direct implications for chip export policy, given that Nvidia's most advanced products sit at the center of the US-China technology contest.

For now, the episode has produced an unusual alignment: a president defending a chief executive his own intelligence agencies had warned him about, a foreign power denying everything, and investors repricing the risk attached to the AI industry's most important company.
